Learn Turkish: Hasetten ölüyordur o gaddar kadın! - That cruel woman is probably dying of envy!

This is a devrik cümle (inverted sentence). In everyday spoken Turkish, the verb doesn't always have to be at the very end. Placing the subject o gaddar kadın after the verb ölüyordur makes it sound like an afterthought or adds a dramatic, colloquial flair, as if the speaker first blurted out the action and then tacked on who they meant.

What does the -dur suffix add to ölüyordur?

Here, the suffix -dur expresses a strong assumption or probability, translating to 'is probably' or 'must be.' While ölüyor just means 'is dying,' ölüyordur means 'I assume she is dying.' At the B2 level, you will see this suffix used frequently with various tenses to show the speaker's deduction rather than a stated fact.

Why does haset (envy) take the ablative suffix -ten (from)?

In Turkish, the ablative case (-dan / -den) is often used to indicate the root cause of a physical or emotional state. Just like you would say soğuktan donuyorum (I am freezing from the cold), you use it here to say hasetten ölüyordur (dying from envy).

Could I use kıskançlıktan instead of hasetten here?
